CBS Announces Titles of “Star Trek Discovery” Episodes 5-9

Star Trek Discovery episode titles 5-9

Names of Episodes 5 Through 9 Announced

Yesterday CBS All Access announced the names of episodes 5 to 9 of Star Trek Discovery in a short video clip on social media sites.

The title of episode 5, Choose Your Pain, was already widely known as broadcasters announce schedules weeks in advance.

As previously reported, episode 9 will be the final episode before the show’s mid-season break.  Episode 10 is scheduled to air in January 2018.

Here’s the video that CBS All Access released.

Here is the list of the five episode titles announced.

  • Episode 5 – Choose Your Pain
  • Episode 6 – Lethe
  • Episode 7 – Magic to Make the Sanest Man Go Mad
  • Episode 8 – Si Vis Pacem, Para Bellum (Translated: If you want peace, prepare for war)
  • Episode 9 – Into the Forest I Go

What might some of the episode names reveal?

We’ve skipped episode 7, Magic to Make the Sanest Man Go Mad.

Episode 5 – Choose Your Pain

We’ve already seen from the episode trailer that Captain Lorca (Jason Isaacs) is captured by the Klingons and imprisoned.  Also imprisoned are Lt. Ash Tyler (Shazad Latif), who we have not yet seen in the series, and Harry Mudd (Rainn Wilson).  It’s possible that Lorca will be forced to make a decision between two necessary evils.  No specifics on what those may be.

Episode 6 – Lethe

The title Lethe likely has to do with another Lethe we’ve seen in Star Trek: The Original Series.  In the TOS episode Dagger of the Mind, the Lethe is a therapist at a rehabilitation colony on Tantalus V.  However before that she was a patient of the rehab colony.  Lethe was noted by Enterprise crew for having little to no expression.  As it turned out, she was experimented on by a Dr. Adams, resulting in her unusual condition.

Lethe was committed to the colony in 2266 – 10 years after Star Trek Discovery‘s first episode takes place.  That means that if the Lethe character does appear in the episode title Lethe, she’s likely to be mentally ill when we meet her.

Episode 8 – Si Vis Pacem, Para Bellum

This episode title may have been a little to on the nose, and therefore the Latin version of it was used.  If we’re to believe Discovery showrunners that the series will represent the optimism that’s a hallmark of any Star Trek series, this may be the turnaround point.

Of course it means things must get worse before they can get better, so expect this episode to be the start of heavy warfare between the Federation and the Klingons, with seeds being sown for peace.

Episode 9 – Into the Forest I Go

Episode 9’s title likely spawns from a quote by John Muir – “And into the forest I go, to lose my mind and find my soul.”

This episode is likely to be a cliffhanger with the rest of the first season continuing after the holiday season.
